The Mitsubishi Group is a group of autonomous Japanese multinational companies covering a range of businesses which share the Mitsubishi brand, trademark, and legacy.

The Mitsubishi group of companies form a loose entity, the Mitsubishi Keiretsu, which is often referenced in Japanese and US media and official reports; in general these companies all descend from the zaibatsu of the same name. The top 25 companies are also members of the Mitsubishi Kin'yōkai, or "Friday Club", and meet monthly. In addition the Mitsubishi.com Committee exists to facilitate communication and access of the Mitsubishi brand through a portal web site.

Hummer was a brand of trucks and SUVs, first marketed in 1992 when AM General began selling a civilian version of the M998 Humvee. In 1998, General Motors (GM) purchased the brand name and marketed three vehicles: the original Hummer H1, based on the Humvee; and the H2 and H3 models that were based on smaller, civilian-market GM platforms.

By 2008, Hummer's viability in the economic downturn was being questioned, and it was placed under review by GM management. Rather than being transferred to Motors Liquidation Company as part of the GM bankruptcy in 2009, the brand was retained by GM, in order to investigate its sale.

In 2009, a Chinese manufacturer, Sichuan Tengzhong Heavy Industrial Machinery Company, announced that it would acquire Hummer, pending government approvals, but later withdrew its bid.On February 24, 2010, Reuters reported that the Chinese ministry of commerce had prevented the deal,although a ministry spokesperson denied rejecting the application, which had been stalled for eight months.At the end of February, General Motors announced it would begin dismantling the Hummer brand.

Although the automaker announced two days later that it had been approached with new offers,by April 2010, any sale became unlikely, as inventory was depleted and Hummer dealerships began shutting down.After filling a rental-car fleet order, the last Hummer H3 rolled off the line at Shreveport on May 24, 2010.
